Yemen's STC says delegation in Riyadh disappeared onto bus and all contact lost

A delegation of over 50 officials from Yemen's Southern Transitional Council (STC) has reportedly disappeared after arriving in Riyadh, Saudi Arabia for talks. The separatist group lost contact with the members, who were allegedly put on a bus by authorities and have not been heard from since. This event coincides with Yemen's internationally recognised government stripping STC leader Aidarous al-Zubaidi of his membership and accusing him of treason. In a related escalation, Saudi-backed forces are advancing towards Aden and have conducted air strikes on Zubaidi's home province.
